The picture shows both a Long Arm and a Short Arm for reference. You will only get a Long Arm L Key.

These are the ones you want to use for your bench if you don't want to buy a swivel top screw driver. The Short Arm ones are perfect for casual hobbiest or as give aways with your folders.

Tip: T5's tend to fit 0-80 and 1-72 screws, T6's tend to fit 2-56, T9's tend to fit 4-40 screws. There is no standard. You might need a T7 or T8 also depending on the screws you are using or knife you are working on.
